Cat's Paw

A man is found murdered.
There’s suspicion the computer system he worked with is involved in an ongoing fraud.
IT consultant Roger Osborne finds himself hurled into the middle of a nightmare when he discovers David Peacock's body in his apartment in Perth. But that is the only the start of a horrific sequence of events that find him and his wife Samantha immersed in fraud and murder as they try to uncover the truth. Only one thing is certain, their lives will have changed irrevocably.
If they survive.
In a similar vein to the films Let Me In & Let The Right One In, there are two versions of this intense thriller, one set in a non-English speaking environment, Saudi Arabia, (green cover); the other set in an English-speaking environment, Australia, (blue cover). The novels are as identical as they can possibly be, the main difference being some of the motivations behind the actions and the scenes.
This is the Australian version.
